Hi guys,

I am modelling a flow of air and CH4.

The gases are supplied to the inlet as follows: 7.3 kg/hr air + 0.43 kg/hr CH4

How can I define this at inlet boundary condition..?

I only seem to have a choice of specifying one of the gases and it's mass flow. I can't do both.

I think mixture model can do this.

Model -> Species Transport

You have to define a mixture material. Then you will have a access to "species" tab in your inlet boundary menu.

Look into theory and user guide, there is good stuff about that.
